+	Added rules listeners
+	* tests/test-extensions/net/sourceforge/jnlp/closinglisteners/CountingClosingListener.java:
+	Base class for closing listeners which is containing complete output in
+	each time.
+	* tests/test-extensions/net/sourceforge/jnlp/closinglisteners/Rule.java:
+	Class with rule definition for RulesFolowingClosingListener
+	* tests/test-extensions/net/sourceforge/jnlp/closinglisteners/RulesFolowingClosingListener.java:
+	ClosingListener consisted from rules which all have to match for close action

+	Implementation of rule based on string
+	* tests/reproducers/signed/AppletTestSigned/testcases/AppletTestSignedTests.java:
+	* tests/reproducers/simple/AppletTest/testcases/AppletTestTests.java:
+	Refactored to use Above iisteners.
